The Impact of Various Compression Ratio and Influence of Bio Additive With Jatropha Methyl Ester Biodiesel in DI Diesel Engine

Abstract

The rapid depletion of petroleum fuels and their ever increasing costs have led to an intensive search for alternative fuels. Also, there was a need to reduce the consumption of diesel fuel in the developed and in the developing countries.The increasing industrialization and innovation of the world lead to a steep rise in the consumption and demand of the petroleum based fuels every year. The experimental work to evaluate the impact of various compression ratio using blends of diesel fuel with 20% concentration of Methyl Ester of Jatropha biodiesel blended with bio additive as an alternate fuel.The experiment was carried out with three different compression ratio in DI diesel engine. Biodiesel was extracted from Jatropha oil, 20% (B20) concentration with 3 ml bio additive is found to be the best blend ratio from the earlier experimental study. The biodiesel B20MEOJBA3 ml is tested with various compression ratio of 17.5, 16.5 and 15.5 respectively. The main objective is to obtain better efficiency, minimum specific fuel consumption and lesser emission using 3ml bio additive blends with biodiesel when compared with baseline diesel.
